DESCRIPTION

Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

As disclosed herein, the term “underpants” refers to any undergarments that have leg structures which extend below the crotch when worn, including, but are not limited to, shorts, briefs, boxers, trunks, thongs, and/or tights.

FIG. 1 illustrates a front perspective view of an exemplary underpants garment 100 of the current disclosure. The underpants include main compartment 105 that provides coverage for the lower torso, including the private parts of the person wearing underpants 100.

As depicted, main compartment 105 includes top opening 110 for the waist and two bottom openings (e.g., elements 120-A and 120-B) for the legs. Underpants garment 100 includes center portion 130. Center portion 130 has opening 135 for the penis to pass through.

The bottom of underpants garment 100 is connected at the center (e.g., via region 140) forming the separation between bottom leg openings 120-A and 120-B.

In some embodiments, underpants garment 100 further includes penis pouch 150. Penis pouch 150 is connected to main compartment 105 via opening 135.

FIG. 2 shows a front view of exemplary underpants garment 200 of the current disclosure. Referring to FIG. 2, front visible parts of underpants 200 include waist band 210, anterior piece 220 (depicted as the area without shading, including two leg panels 230 and center piece 240), bottom crotch piece 270, and front auxiliary piece 280.

Bottom side of waist band 210 connects the top of anterior piece 220 (which includes leg panel 230-A, center piece 240, leg panel 230-B, optional side panels 290) and the top of posterior piece 310 (see FIG. 3). In some embodiments, waist band 210 is elastic. The width of waist band 210 can also vary with the type of underpants. For example, a pair of boxers may have a wider waist band than a pair of briefs does. In some embodiments, waist band 210 is circular and connected to both anterior piece 220 and posterior piece 310.

In some embodiments, anterior piece 220 includes three parts: two leg panels (e.g., elements 230-A and 230-B in FIG. 2) and center piece 240 that covers the crotch area. The size and shape of leg panels 230-A and 230-B vary with the type of underpants. For example, leg panels 230 for a pair of boxers would be wider and longer than those for a pair of briefs.

In some embodiments, leg panels 230-A and 230-B are connected to side panels 290-A and 290-B, respectively. In some embodiments, side panels 290 are made of fabrics with ventilation properties. In some embodiments, side panels 290 are decorative and of different colors from anterior piece 220 and posterior piece 310.

In some embodiments, center piece 240 includes opening 255 that allows the penis to pass through. In some embodiments, opening 255 is positioned such that the vertical center line of the center portion (and of the underpants) goes through the center of opening 255. As disclosed herein, opening 255 can adopt any suitable shape and size. For example, opening 255 can be circular or oval. In some embodiments, opening 255 can have straight sides. In some embodiments, opening 255 can have straight sides with curved top and bottom.

In some embodiments, center piece 240 of anterior piece 220 includes top panel 250 and bottom panel 260. In some embodiments, opening 255 is located within top panel 250. In some embodiments, top panel 250 is a single piece of fabric bearing opening 255. In some embodiments, top panel 250 includes multiple pieces of fabric.

In some embodiments, bottom panel 260 of center piece 240 is a loose sac. In some embodiments, the sac is made with loose and flexible fabric. The sac is designed to accommodate the scrotum. In some embodiments, the scrotum sac is made with fabrics having ventilation properties. For example, the fabric can be a natural or synthetic material bearing mesh structures. A separate scrotum sac provides mechanical support for the scrotum, preventing diseases such as varicocele. Mechanical support for the scrotum is critically important when the wearer is in a motion state; for example, when playing sports.

In some embodiments, underpants garment 200 further includes front auxiliary piece 280. In some embodiments, auxiliary piece 280 forms a penis pouch that covers opening 255 of center piece 240. For example, auxiliary piece 280 can be sewn to center piece 240 along its borders. In some embodiments, one or more gaps are intentionally left in the seams along the borders of auxiliary piece 280. The one or more gaps can provide ventilation. In preferred embodiments, the bottom of auxiliary piece 280 includes a bottom ventilation gap, leaving an opening between the bottom of the penis pouch and the lower portion of the anterior piece (e.g., the scrotum sac). This concealed design covers the penis in the flaccid state or erected state. More importantly, the bottom ventilation gap is at a center location and allows easy extraction of penis for urination. There is no need to bend or twist the organ such as with underpants with a side opening. In addition, the user does not need to take off the underpants garment.

Interior sides of leg panels 230-A and 230-B and the bottom side of bottom panel 260 of center piece 240 are connected to bottom crotch piece 270. Bottom crotch piece 270 forms the bottom of underpants 200 and separates the two bottom leg openings. In preferred embodiments, bottom crotch piece 270 is formed by a single piece of fabric. In general, bottom crotch piece 270 is large enough to provide comfort. It will be understood that the size of bottom crotch piece 270 varies with the type of underpants 200.

FIG. 3 shows an exemplary embodiment of underpants 300. Here, anterior piece 220 and posterior piece 310 are separated from each other on the side, but remain connected at the bottom via bottom crotch piece 270. In FIG. 3, front auxiliary piece 280 is removed to reveal details of center piece 240 that has been covered in FIGS. 1 and 2.

As depicted, FIG. 3 shows anterior piece 220 and posterior piece 310 separated from each other at the seams along the two sides of posterior piece 310. Here, anterior piece 220 remains connected on either side to a side panel 290.

In some embodiments, anterior piece 220 comprises two leg panels 230 (230-A and 230-B) and a center piece 240. Each leg panel 230 is connected on the interior side to center piece 240 and on the exterior side to side panel 290. In some embodiments, ventilation properties can be added through the use of side panels. For example, it is possible to use regular materials to construct anterior piece 220 and posterior piece 310 and to use materials with good ventilation properties for the side panels. In some embodiments, materials with mesh structures are used to make the side panels. In these embodiments, heat and moist accumulated in the main compartment can be released through the side panels, ventilation gaps on the top and side of the penis pouch (as illustrated in FIG. 4), the ventilation gap between the penis pouch and the scrotum sac. The designs implementing these features can provide comfort to athletes during active sports.

The top of leg panels 230 and center piece 240 are joined in one continuous seam along the bottom edge of waist band element 210-A. The top of posterior piece 310 is connection in one continuous seam along the bottom edge of waist band element 210-B. Elements 210-A and 210-B join together to form a circular waist band 210. In some embodiments waist band 210 is one continuous piece. In some embodiments, waist band 210 is elastic. The size and shape of leg panels 230 can vary with the type of underpants. For example, a pair of loose boxers have longer sides, wider bottoms and loose leg space. A pair of briefs may have shorter sides and bottoms as well as tighter leg space.

In some embodiments, the bottom of leg panels 230 and center piece 240 are joined in one seam along one side of bottom crotch piece 270. In some embodiments, little or no part from each leg panel 230 is connected with bottom crotch piece 270 (see, e.g., FIG. 8). In some embodiments, bottom crotch piece 270 is connected on one side only to the bottom of center piece 240 and on the other side to the bottom of posterior piece 310. As disclosed herein, bottom crotch piece 270 is a single piece of fabric. In particular, bottom crotch piece 270 is positioned such that, when a person is wearing a pair of underpants of the current disclosure, the seams connecting bottom crotch piece 270 to anterior piece 220 and posterior piece 310 are not in direct contact with the scrotum or other parts near or at the crotch area. Such a configuration avoids friction between sensitive body parts and bottom crotch piece 270 to provide maximum comfort.

In some embodiments, center piece 240 includes top panel 250 and bottom panel 260. In some embodiments, top panel 250 includes two pieces (e.g., elements 250-A and 250-B in FIG. 3), each bearing a cutout shape for forming half of opening 255. In alternative embodiments, top panel 250 includes a single piece that bears a cutout shape for the opening. In some embodiments, opening 255 is positioned such that the vertical center line of the center portion (and of the underpants) goes through the opening. As disclosed herein, opening 255 allows the penis to pass through in either erected or flaccid state and can adopt any suitable shape and size. For example, opening 255 can be circular or oval. In some embodiments, opening 255 can have straight sides. In some embodiments, opening 255 can have straight sides with curved top and bottom. In some embodiments, the edge of opening 255, in particular the bottom edge, is padded to provide comfort.

In some embodiments, bottom panel 260 of center piece 240 includes two pieces (e.g., 260-A and 260-B in FIG. 3). In some embodiments, bottom panel 260 is made of loose fabric to form a sac or pouch for holding the scrotum. Bottom panel 260 separates the scrotum from the penis.

FIG. 4 provide a close-up view of auxiliary piece 280 and center piece 240 that is at least partially covered by auxiliary piece 280. As disclosed above, front auxiliary piece 280 covers the opening (e.g., element 255 in FIG. 3) in center piece 240 and forms an enclosed pouch for the penis. Front auxiliary piece 280 is attached to the anterior piece by discontinuous seams along the border of the front auxiliary piece, and front auxiliary piece 280 completely covering the opening (e.g., element 255 in FIG. 3). In one embodiment, the discontinuous seams contain one ventilation gap; in other embodiments, the discontinuous seams contain two or more ventilation gaps. In certain embodiments, front auxiliary piece 280 has a top ventilation gap 282. In some embodiments, front auxiliary piece 280 has two side ventilation gaps: 286-A, and 286-B. Auxiliary piece 280 forms a front penis pouch with the center piece such that the inside of the main compartment of the male underpants garment and the interior space of the front pouch form a continuous space via opening 255 in center piece 240. In some embodiments, bottom part 284 of front auxiliary piece 280 is folded inwardly to for a pouch for the placement of penis. In some embodiments, there is a ventilation gap between the bottom of front auxiliary piece 280 and a scrotum sac that is formed at the bottom of center piece 240

In some embodiments, front auxiliary piece 280 (and the penis pouch) has a smaller top dimension and a larger bottom dimension. Such dimensions provide optimal accommodation of the penis in either the flaccid or erected state. In other embodiments, front auxiliary piece 280 (and the penis pouch) has similar top and bottom dimensions. In some embodiments, front auxiliary piece 280 (and the penis pouch) has a smaller top dimension, a larger center dimension and a smaller bottom dimension. In all embodiments, the penis pouch has more depth toward the center and bottom for better accommodation of the penis.

As disclosed above, the pouch provides space for the penis in both erected and flaccid states. As depicted in FIG. 4, the top portion of the penis pouch has a dimension that is smaller than the bottom portion of the pouch. When the penis is in the erected state, it extends upwards into the smaller top portion. The dimension of the pouch helps to set the organ straight, without rolling to either side. When the penis is in the flaccid state, it falls into the larger bottom portion. Separation of the penis from the scrotum is maintained in either state.

FIG. 5 shows a bottom view of one exemplary embodiment 500, illustrating an exemplary bottom crotch piece 270, which separates leg openings 120-A and 120-B. In some embodiments, bottom crotch piece 270 is a single piece of fabric. In other embodiments, bottom crotch piece 270 features a multi-piece design. The addition of this separate crotch piece 270 provides spacious room, which reduces or eliminates pressure from the crotch area for the wearers. In some embodiments, crotch bottom piece 270 is made of materials with mesh structures, providing good ventilation for the genitalia.

The designs disclosed herein are advantageous in emuerous aspects. For example, they provide mechanical support for the scrotum, separate the penis and scrotum (and the groin area) in different compartments, provide a corrective function for the penis in either the flaccid or erect state, ensure a good ventilation to the genitalia, and allow easy extraction of penis without taking off the underpants garment. It would be understood that embodiments disclosed can be applied to any underpants garments that have leg structures which extend below the crotch when worn, including, but are not limited to, shorts, briefs, boxers, boxer briefs, trunks, thongs, and/or tights.

FIG. 6 is the front view of an embodiment of the underpants garment in the form of a pair of briefs. The underpants include a main compartment that provides coverage for the lower torso, including the private parts of the wearer. The main compartment includes top opening 610 and bottom openings 620-A and 620-B for the legs. Underpants garment 600 includes center portions 630-A and 630-B, with an opening for the penis to pass through. The bottom of underpants garment 600 is connected at the center (e.g., via region 640) such that two bottom leg openings 620-A and 620-B are separated from each other. In some embodiments, underpants garment 600 further includes penis pouch 650, which is connected to main compartment via the opening. Due to the overall tight configuration of this embodiment, the front auxiliary piece and penis pouch adopt a different shape from the design shown in previous embodiments. Specifically, the pouch has a small top horizontal dimension that gradually increases until the opening position. The horizontal dimension of the pouch further decreases below the opening position to the bottom. In some embodiments, the bottom of the penis pouch is made of loose fabric for comfortable accommodation of the penis. In most embodiments, loose fabric forming the bottom of penis pouch 650 provides a depth for comfortable accommodation of the penis. FIG. 7 shows a side perspective view of one embodiment of an underpants garment in accordance to the current disclosure, illustrating how several important designs are featured in a relatively tight underpants garment. Here, bottom ventilation gap 660 is formed between the front penis pouch and scrotum sac 640 (the scrotum sac is part of the main compartment of the underpants garment). The penis in a flaccid state falls naturally into the bottom ventilation gap in the penis pouch. The penis, the scrotum, and the groin area are isolated from each other: the penis is in a separate pouch, although the scrotum and the groin area are both in the main compartment, the scrotum is kept in a localized sac that is relatively isolated from the rest of the main compartment. The center position of the bottom ventilation gap helps to set the organ straight, without rolling to either side. Importantly, the ventilation gap allows easy extraction of the penis for urination without taking off the underpants.

FIG. 8 shows an exemplary embodiment of underpants 800. Front auxiliary piece is removed to reveal details of anterior pieces 730-A and 730-B. Bottom side of waist band 710 connects the top of side panel 790, anterior piece 720, and the top of posterior piece 770. In some embodiments, waist band 710 is elastic. The width of waist band 710 can also vary with the type of underpants. For example, a pair of briefs may have a relatively narrow waist band. In some embodiments, waist band 710 is part of anterior piece 720 and posterior piece 770. For example, the top of anterior piece 720 and posterior piece 770 can be folded to form a circular pocket for housing an elastic band. In other embodiments, an elastic band is sewn directly to the top of anterior piece 720 and posterior piece 770.

In some embodiments, there are no separate leg pieces in the anterior part of the underpants such as in a tight design of a brief embodiment. Anterior piece 720 is connected to side panels 790, respectively. In some embodiments, side panels 790 are made of fabrics with ventilation properties. In some embodiments, side panels 790 are decorative and of different colors from anterior pieces and posterior pieces.

In some embodiments, anterior piece 720 include opening 750 that allows the penis to pass through. In some embodiments, opening 750 is positioned such that the vertical center line of the anterior piece goes through the opening. In some embodiments, anterior piece 720 includes top panels 730-A and 730-B, and bottom panels 740-A and 740-B. In some embodiments, opening 750 is located within the top panels.

In some embodiments, bottom panels 740-A and 740-B of the anterior piece 720 form a sac for accommodating the scrotum, separating it from the groin area. In some embodiments, the sac is designed to accommodate the scrotum and made with loose and flexible fabric. In some embodiments, the scrotum sac is made with fabrics having ventilation properties. In some embodiments, a single crotch piece 760 is joined with bottom panels 740-A and 740-B on one side, and with posterior piece 770 on the other side.

FIG. 9 provides a close-up view of auxiliary piece 650 and center piece 720 that is at least partially covered by the front auxiliary piece 650. As disclosed herein, front auxiliary piece 650 covers opening 750 and forms an enclosed pouch for the penis. Auxiliary piece 650 is sewn onto center piece 720 along its borders. In some embodiments, the seams along the borders are discontinuous and contain one or more ventilation gaps that can provide good ventilation. In some embodiments, front auxiliary piece 650 includes a top ventilation gap 652. In some embodiments, front auxiliary piece 650 includes two side ventilation gaps: 656-A, and 656-B. Front auxiliary piece 650 forms a front pouch such that the inside of the main compartment of the male underpants garment and the interior space of the front pouch form a continuous space connected via opening 750 in the anterior piece. In some embodiments, front auxiliary piece 650 has similar top and bottom dimensions.

The designs disclosed herein are advantageous over existing products being sold on Amazon, which are disclosed in Chinese Patent No. CN202774143U issued in 2013 and Chinese Patent No. CN204335838U issued in 2015.

Chinese Patent No. CN202774143U discloses a design of male underpants that separates the penis, the scrotum and the crotch area from each other. The space is most suitable for accommodating the penis in its flaccid state. However, when the penis is in the erected state, it is pressed against the outer cloth. The resulting pressure can cause the organ to bend, leading to discomfort and possible adverse consequences. Adult penises tend to roll to the left or right, in either flaccid or erect state. In severe cases, such side-rolling can affect physiological functions of the penis. The penis pouch disclosed in Chinese Patent No. CN202774143U does not have a defined shape and cannot provide corrective function to penises that tend to roll to the side. The design includes only one ventilation gap, which does not lead to good ventilation to keep the genitalia in a cool and dry state.

Chinese Patent No. CN204335838U discloses a straight tube-like pocket for holding the penis when it is erected. When the penis is in the flaccid state, it cannot extend into the penis pocket. Instead, the penis falls naturally through the opening back to the main compartment and is pressed against the scrotum. The design loses the separation function. The penis is mostly in the flaccid state, so most of the time, the design cannot achieve the separation function. The scrotum is very sensitive to moisture and temperature, this requires a good ventilation. The only ventilation gap locates on the top, which does not fulfill the requirement of keeping the scrotum at a cool and dry state. As such, the design in Chinese Patent No. CN204335838U does not allow an easy extraction of penis without taking off the underpants, which causes inconvenience.

The current designs are developed based on feedback from customers of the two prior designs and cure various deficiencies of the prior designs. A series of experimental designs were tested by professional test-wears. Indeed, the current designs precisely address existing defects of the prior designs and offer improvements over both designs.

Disclosed embodiments in this application feature numerous benefits. A separate scrotum sac provides mechanical support for the scrotum, preventing diseases such as varicocele. The mechanical support for the scrotum is critically important when the wearer is in a motion state during active sports. Fabrics with good ventilation properties are used to make the pocket to ensure that the scrotum is in a cool and dry state. An opening in the insert center piece(s) separates the penis from scrotum, a penis pouch formed by the insert pieces and front auxiliary pieces provides a separate space for the placement of penis. The penis, the scrotum, and the groin area are separated from each other in different compartments or different parts of the same compartment. Contact and frictions between different organs are effectively avoided, which helps to prevent diseases such as eczema. The seams between front auxiliary pieces and insert center pieces is discontinuous, with especially large gaps on the two sides. The design of side panels allows extra ventilation properties to be added (through use of materials of good ventilation properties). In some embodiments, materials with mesh structures are used to make the side panels. Heat and moist accumulated in the main compartment can be released through the side panels, ventilation gaps on the top and side of the penis pouch (as illustrated in FIG. 4), the ventilation gap between the penis pouch and the scrotum sac. Such designs implementing these features can provide comfort to athletes during active sports.

The penis pouch in the disclosed embodiments also features other advantages. For example, the top, side and bottom ventilation gaps allow quick release of heat and moist. A penis at its erect state freely protrudes into the top portion of the penis pouch without being pressured. Small dimension of the top portion of the penis pouch helps to maintain the erected penis in the right position, providing corrective functions. When in the flaccid state, the penis naturally falls into the larger bottom portion of the penis pouch. The center position of the bottom gap with a tight design provides correction functions for the penis in the flaccid state. Furthermore, a bottom ventilation gap allows easy extraction of the penis for urination without taking off the underpants garment. Lastly but very importantly, adding a separate bottom crotch piece provides a horizontal expansion for the spaces of the featured penis pouch, scrotum sac, and the underpants garment as a whole. Ventilation is further improved by the further expanded design benefited from the crotch piece. Pressure on the genitalia is avoided for people who have strong and bulky muscles or are overweight, thus preventing possible discomfort to such users.
